FURNITURE ATTACHMENT.

Application filed March 23, 1926. Serial N0. 96,812.

This invention relates to furniture attachments and has particular reference to tightening devices therefor.

An important object-of the invention "is to provide'a device of the above character which may be mounted in association with chalr legs and the like for bracing the legs and retaining same firmly in association with the cha1r frame. 7

A further object of the invention is to provide a device of this character which may be.

' numerals are employed to designate correspondin parts throughout the same:

Figure 1 is a side elevation of the lower portion ofa chair frame, a portion thereof being broken away showing my improved device mounted in association therewith,

Figure 2 r is a horizontal sectional view taken on the line2 2 of Figure 1,

Figure 3 is a sideelevation showing a portion of my improved device mounted in association with a table leg,

Figure l is a top plan View showing the device used in connection with the side boards of abed, v

Figure 5 is an enlarged top plan view showing a modified form of the device, and a Figure 6 is a perspective view of one of the bracket members used in connection with my device. in f In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of my invention, th e'numeral 10 generally indicates the legs of a conventional type of chair usually employed in offices.

cured at their inner ends by suitable brackets, each of the legs extending radially from the center post ofthe chair. It is apparent that Y the entire weight of the structure and person sitting therein will be imposed upon thepost and the adjacent connecting ends of the legs will have a tendency to sag downwardly,

thereto, 7 vided with heads 20 of substantially semi To overcome this, I provide a tightening device tobe readily associated with the legs to prevent spreading thereof and ultimate collapse of the chair.

. Referring now more particularly to the structure embodying my invention, the numeral 11 generally indicates a securing bracket embody ng a longitudinal base plate 12 curvedat one end so as to conformto the lower edge of the chair legs. ,The contacting face of the longitudinal base plate 12 is provided with a h1g1?) of circular cross section extending from the central portionfof the base plate and adapted to seat in a suitable, recess formed'in'the leg so as to prevent lat- F e'ral movement of the bracket. The opposite side of the base plate is provided with a boss 14, an opening 15 being formed transversely in the boss and a groove 16 being formed in one face thereof and communicating at one end with the here so as to receive a suitable retaining member to be described more fully hereinafter. The plate 12 is provided adjacent its extremities with apertures 17 adapted to receivewood screws 18 for securely mounting the plate upon chair legs and the like. In using my improved apparatus in association withchairs, a bracket 11 is secured to each leg of the chair, as shown to advantage in Figure 1. The bosses-l4: project'down- 'wardly, and longitudinal adjusting rods 19 are mounted through thetransverse bores in these bosses, the outer extremities of the rods being threaded .for'th e application ofnuts The inner ends of the'rods are pro-- circularformation to permit convenient connection' with. a central retaining member 21.

This 'retaining member 21 is preferably in the form of a circular ring provided with a plurality, in the present instance four, elongated slots 22 through which the inner ends of the rods 19 are mounted. The retaining rods19 are preferably square in cross section adjacent the heads so that the rods will be held againstrotation while the nuts,.on the outer ends of the rods, are being adjusted. ,As clearly shown 111 Figure '1,'the retaining 'These legs are of angularvformationand se-i ring-21 is preferably large enough to easily accommodate the adjusting screw of the chair so that this screw may be vertically modified application of the device is illustrated, theclamp 11 isshown secured'to the vertical leg of a table, designated by the numeral 23, the inner side of the leg in this instance being slightly recessed to receive the curved portion of'the bracket. A particular form of retaining rod'l9"is employed-in this application of the attaclnnentflhe outer end of the rod being provided with ananp'ular extension adapted to iit the bore l5 or the bracket WhlCll assumes a vertical positien.

The inner ends of these rods 19 are also threaded to permit application; or thereto. These reds are adj ends Within theretaining, 21 so that the legs of the table or similar article may be braced in position. V I

Still an hei application oi the attachment is shown a Figure 4e, this fern-r empl ying rods 19' similar to those employed in connec- :tion With tables and the like the oracle 11 being secured in mitable spaced relation.- to the side boards 2 oi? a bed to prevent dis torti-on, of these m mbers? It can. be readily seen that my improved attaclnnentmay be very rea 'ly employed upon various articles of iue'niture so as to firmly brace the supporting members and materially prolong'the li l'e of the article.

of the invention or the scope of 'theesubjoined claims, 7

Having thus described my invention, I claim: V V

l. A furniture attachment comprising, in combinationga plurality of connecting rods threaded their outer ends and provided With heads at their inner ends, a ring member provided with openings receiving the inieted at t einner:entensionsbeing screw thre,

ner ends of the rods, bracket members each including a reta ning plate, a lug iiormed on the inner side of the retaining plate, and a shoulder extending from the outer side of the plate provided with an opening therethrough, receiving the outer end of the respect-i ve rod.

2.. A furniture attachment comprising, in

combination, a plurality of rods provided at their outer endswith angular extensions, the

ring provided with a' plurality o t ope the inner ends of the reds, heads on said ends of the rods engaging the inner sides of the ring and brach each including an attaching' piate, a ll \ned on a i v panel a long tudinal commu-nical-ong groove 1 aectijvel'y receiving the end of the respect/me rod and the gular extension thereof.

3. Ai'device of the class desci "be-d comprisn-er ends through the slots and radiating from the said member, the said rods being; provided their said inner ends with headsengaging the inner side of the ,member and the said inner ends of the rods being: squared at their portions which. engage in the slots whereby to restrain the rods from rotative movement, a plurality of brackets attachable to members to be braced, each bracket having a portion apertured to accommodate the outer endof a respective one of the rods, the

outer end of each rod being threaded, and a nut adjust-ably threaded onto the outer end of each rod andcoactmg with the said portion of the respective bracket.
